you can use limit 1

insert feedback_analysis (service,type,feedback)          values ((select data                  webform_submitted_data                  nid=20 , cid=5                  limit 1),                 (select data                  webform_submitted_data                  nid=20 , cid=3                  limit 1),                 (select data                  webform_submitted_data                  nid=20 , cid=4                  limit 1));
